Split shed motion for looms



April 1931- H. L. BETZLER SPLIT SHED MOTION FOR LOOMS Filed April 21, 1930 Patented Apr. 14, 1931 a. UNITEDiSTATES HERMAN L. BETZLER, or WILKES-BARBIE, PENNSYLVANIA PATENT OFFICE SPLIT SHED MOTION FOR LOOMS Application filed' April 21,

The present, invention relates to split shed motions for looms, and comprehends means wherebythe operation and control of the loom harness is regulated in a manner to provide a better, more even and tightly woven fabric.

In carrying out my invention I contemplate accelerating the movements of some harness frames with relation to others, and at predetermined intervals during the course of their travel, thereby efi'ectively separating the ends of the warp threads with a brushing efl'ect, freeing the same of'lint and the like, and also preventing floatsand end break ing the warp threads.

The chief characteristic of the present invention resides in-the regulation and control I of the loom harness forthe above mentioned purposes, incident to each operation ofthe lay. i

Again, the invention is primarily in the nature of a loom attachment, in that it can be incorporated in any well known type of loom without requiring any alterations of the latter. V

The nature and advantages of the invention will be better understood when the following detail description is read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of thls application like numerals of reference indicate similar parts in the several views and where- Figure 1 is a view in elevation and partly in section illustrating the application of the invention.

Figure 2 is afragmentary diagrammatic view showing how the invention is connected with the lay sword. r

. Figure 3 is a fragmentary detail view of a the connection between the reciprocating rod and the turn buckles of the attachment.

Referringto the drawing in detail 10 and 11 respectively indicate the harness frames 1930. Serial No. .e1i6,032.

which are supported by cables 12 and 13 trained over suitable guide pulleys 14 supported by the arch or frame of the loom herein indicated at'15. The cables 12 and 13 re spectively'are connected with the jacks l6 and 17 respectively of ordinary construction and these jacks are operated in the usual well known manner. The lay is indicated at 18, while the lay sword is indicated at 19, the latter being actuated in' the ordinary well known manner. The construction thus far described is well known, and does not form any partof the present invention, the latter as above statedresiding in the provision ofa novel construction of means to regulate and control .the movements of the harness frames, in a manner whereby some of the frames are accelerated and others retarded during their course of travel, and incident to each operation of the latter. i

While the cables 12 and 13 may be connected with thejacks 16 and 17 in any suitable manner, I preferably form each cable with a loop received by an'eye 20 formed on one end of a link 21. There is a link foreach cable, and each link is connected with 2 its respective jack by a substantially U- shapedmember 22. i

The present invention contemplates a connection between the cables 12 and 13 and the lay sword19, so that upon each operation of the lay sword, those harness frames moving in an upward direction are accelerated, while those moving in a downward direction are retarded at a time when the harness specified, I have illustrated a specific embodiment of the invention which embodies an operating rod 22 suspended from the corresponding ends of the turn buckles 23 which Y 7 provides a connection between theturnbuck- Ice and operating rod 22; A bolt 27 ispassed through the eyes 24: and also throughthelink thereby providing a pivotal joint between the turn buckles and the'operating rod 22'.

It will be further observed thatthe invention is of'such character that it can be incorporated in well known looms in present 'day use, without making any alterations in the latter necessary, and will materially increase theeliiciency of the loom, giving comparatively far better results and at the same time minimize the work andlabor of those operating the loom. y i
